You can create an In-Stream audio ad using either the DAAST or VAST format. The format type depends on the site's media player; not all media players consume DAAST, but many advertising-enabled media players support VAST audio ads. Sizmek supports VAST 2.0, 3.0, and 4.1 audio ads.
For both DAAST and VAST formats, you can upload any type of linear assets that the publisher supports, for example, .mp3, .ogg, or .avi files. Several different file format variations can be attached to a single audio ad. Sizmek recommends attaching .mp3 files to all ads, unless the publisher rejects .mp3 files.
Important
Important: Before you begin, make sure that you verify the site's audio ad-ingestion capabilities with your customer success manager.
DAAST inherits directly from VAST 3.0. With a few minor changes, DAAST XML structure, features, naming conventions, associated functionality, and trackers are almost the same as VAST.
The main differences are the following:
DAAST <AdInteractions> node replaces VAST <VideoClicks>.
DAAST wrapper replaces VAST <VASTAdTagURI> with <DAASTAdTagURI>.
DAAST does not support non-linear audio ads.
Note
Note: Sizmek does not support the following DAAST <Companion> node optional attributes: logoTile, logoTitle, logoArtist, and logoURL.
Note
Note: Auto-transcoding is not supported for audio files. Audio files must be transcoded according to site specifications prior to uploading your ad. For more information, see Work with Video Auto-Transcoding in Sizmek Ad Suite.
In Sizmek Ad Suite (SAS), click Creative >Ads> New Ad >Blank Ad to create a new master ad.
